Define notations[edit]

In the section 'algorithm', please define what are $f$ , $\delta _{t}\,\!$ , the index $i$ . People can't guess, unless they allready know about LB... —Preceding unsigned comment added by 81.64.81.88 (talk) 07:17, 29 April 2011 (UTC)[reply]

Only CFD?[edit]

I am no expert on the field, but from what I've gathered, CFD is not the sole application of lattice-Boltzmann methodology; e.g. Succi (the very same as referenced in the article) has done work on computational quantum mechanics with LBM. LBM in magnetohydrodynamics also seems to be a rather big field of study (is magnetohydrodynamics a subset of CFD, though?). There are a bunch of other computational fields benefiting from the LBM-approach: Would this be worthwhile of mentioning? —Preceding unsigned comment added by ALambda (talk • contribs) 19:20, 28 November 2008 (UTC)[reply]

Boundary Conditions[edit]

Can someone add a boundary conditions section? I have not gotten to that in my readings yet. Thanks.

Deeper explanation and derivation[edit]

Can the more intelligent physics students add a more thorough discussion to the math section. I have a moderately good group but adding all these equations is exhausting. Also, I know the derivation from the LBE equation to Navier Stokes but if someone wants, can they throw that in there?

Graphics[edit]

Some pictures of the lattices would be good to see. Most papers have them and should be just some copy and paste for the DnQm section.

what about taking pictures from http://www.scholarpedia.org/article/Lattice_Boltzmann_Method ? The article is under creative commons. The pictures there too? Further i would suggest to use even more pictures in the rest of the text.--92.205.45.139 (talk) 22:03, 12 October 2013 (UTC)[reply]

Still a good idea! yoyo (talk) 16:02, 19 April 2017 (UTC)[reply]

When faced with good idea, a central tenet of Wikipedia's philosophy is that you should 'be bold', and make a start on making those changes yourself! (If you have the time and skill.)

Nevertheless, in general it is not safe to literally "copy and paste" from others' publications, as this would be at serious risk of copyright infringement. Elements published under Creative Commons licences are often OK to include, although to be sure a closer inspection of the precise type of Creative Commons licence needs to be made. For example: "Works distributed under the Creative Commons Non-Commercial license are not compatible with many open-content sites, including Wikipedia, which explicitly allow and encourage some commercial uses." (see Creative Commons criticisms).

Utility of the derivation of the Navier–Stokes equation[edit]

In Lattice Boltzmann methods § Derivation of Navier–Stokes equation from discrete LBE, the article presents an overly detailed process of mathematical manipulation, most of whose steps are lacking motivation, even when they wouldn't be totally opaque to an interested lay reader. Surely an article of this sort need do no more than:

state that such a derivation is possible, and
(ideally) include reasons why having it is worthwhile?

The details of this derivation really belong in an engineering methods manual - they're pretty close to a "how-to" guide. So, I think we should remove them - or at least make them support the kind of statement I described above. What use is the derivation to our (non-specialist) audience? yoyo (talk) 16:17, 19 April 2017 (UTC)[reply]

Development from the LGA - method missing words[edit]

The last sentence in "Development from the LGA" is incomplete. Flüssigkristall (talk) 07:40, 11 May 2021 (UTC)[reply]

Semi-protected edit request on 27 September 2021[edit]

This edit request has been answered. Set the |answered= or |ans= parameter to no to reactivate your request.

The last sentence of the second paragraph of section "Development from the LGA method" begins with "In addition, th also ". "th" is not a word, I'm am not sure what was intended to be written here, so I will leave it to another person to decided how this sentence should be written. Mathew Lewis (talk) 18:58, 27 September 2021 (UTC)[reply]

Partly done: I just removed the sentence, as it's unsourced and I couldn't suss out the meaning. ScottishFinnishRadish (talk) 15:10, 28 September 2021 (UTC)[reply]

Limitations section is not neutral[edit]

The Limitations section is written in an argumentative style, with every single limitation followed by a counterargument. This gives the false impression that there are no real limitations of LBM, only unsolved problems due to its infancy. I am not familiar enough with LBM to rewrite this section, but there are undoubtedly genuine, fundamental limitations with the approach, e.g. it is only really useful for a limited subset of fluid problems, usually at relatively small spatial scales. The last two sentences also violate WP:SYNTH. Scleractinian (talk) 22:30, 6 March 2024 (UTC)[reply]
